Definitions
- the present invention relates to an aqueous composition with good stability in which moisture transpiration is suppressed from an aqueous phase.
- compositions containing water as a base there are many compositions containing water as a base, and such aqueous compositions prevent water from evaporating from the composition. Therefore, in many cases, the composition is stored in a closed container.
- water gradually evaporates from the aqueous composition, which may cause changes in physical properties or discoloration.
- spray-type containers, pump-type containers, etc. the discharged contents remain at the discharge port and dry near the discharge port, so the contents attached to the discharge port cause discoloration and odor, There was a problem of worsening the feeling of use. Further, the contents are dried and solidified, resulting in clogging, and in some cases, there is a problem that ejection is impossible.
- a non-volatile liquid oil is used for at least one selected from solid substances and / or film-forming polymers at 25 ° C. or lower. It has been proposed to blend at a specific ratio (see Patent Document 1). However, in order to suppress the solidification of the contents, it is necessary to add a large amount of non-volatile oil agent, and the dosage form is limited. Moreover, even if it mix
- skin care cosmetics such as a milky lotion, a cosmetic liquid, and a cream are widely used as a skin external preparation that moisturizes the skin and imparts flexibility.
- These external preparations for skin mainly contain polyhydric alcohols, water-soluble water-soluble polymers and oils, and the water-holding power of polyhydric alcohols and water-soluble water-soluble polymers themselves increases the moisture on the skin.
- Moisturizing effect is intended to be obtained by keeping it on the skin without being released into the outside air by keeping it for a certain period of time or by a thin film that oil or the like forms on the skin, without releasing the water that evaporates from the skin.
- non-polar oils such as petroleum jelly and liquid paraffin are generally less compatible with sebum, so they slip on the skin even after application, have a slimy feel, and the oil moves to touched clothes and paper etc. There was a problem.
- cosmetics such as foundations in which powders are blended, there is a problem that when the applied skin touches the clothes, the powders easily transfer to the clothes.
- the present invention includes the following components (A), (B) and (C): (A) a polyoxyethylene alkyl or alkenyl ether in which the alkyl group or alkenyl group has 20 to 24 carbon atoms and the average added mole number of ethylene oxide is 1.5 to 4;
- the present invention provides a water-based composition in a container containing (B) a water-soluble polymer and (C) water.
- the present invention also provides the water-based composition in a container further containing the component (D) skin active ingredient.
- the present invention also includes the following components (A) and (B): (A) a polyoxyethylene alkyl or alkenyl ether in which the alkyl group or alkenyl group has 20 to 24 carbon atoms and the average added mole number of ethylene oxide is 1.5 to 4; (B) A water transpiration inhibitor from an aqueous composition containing a water-soluble polymer as an active ingredient is provided.

And (B) a method for suppressing moisture transpiration from an aqueous composition characterized by containing a water-soluble polymer.
- FIG. 8 It is a figure which shows the state of the pump after 30-day progress of Example 8 and Comparative Example 8.
- FIG. It is a graph which shows the change of the stratum corneum moisture content in Test 8. It is a graph which shows the change of the transdermal moisture transpiration amount in Test 8.
- the problem of the present invention is to suppress solidification and property change of the contents by suppressing moisture transpiration of the water-based composition in the container, excellent in stability over time, even when used for spray containers and pump containers.
- An object of the present invention is to provide a water-based composition in a container that can suppress the clogging by suppressing the drying of the contents attached to the discharge port.
- a further object of the present invention is to provide a composition that, when applied to the skin, does not feel sticky, has a refreshing feel, is well-familiar with the skin, and achieves excellent occlusion.
- the present inventor found that water transpiration from the aqueous composition was caused when a water-soluble polymer and polyoxyethylene alkyl or alkenyl ether were used in combination.
- the polyoxyethylene alkyl or alkenyl ether can be remarkably suppressed, and the polyoxyethylene alkyl or alkenyl ether having an alkyl group or alkenyl group having 20 to 24 carbon atoms and an average addition mole number of ethylene oxide of 1.5 to 4 was used.

- ⁇ S stratum corneum moisture change
- the stratum corneum moisture content is synergistically improved.
- the stratum corneum water content a significant improvement effect was seen by using the component (A) as compared with the preparation containing the component (D). This is because the component (D) acts inside the skin in a state where the epidermal lipid and water-soluble components are forcibly removed by the artificial rough skin treatment, and the component (A) is the surface of the epidermis. By covering the skin and preventing transpiration, it may be possible to lead the skin state to a better state.

表7記載の実施例9、比較例9、10の製剤をそれぞれ100μlずつ、親水性メンブランフィルター(MF-ミリポア GSWP02500、日本ミリポア社製;孔径0.22μm、フィルター直径15mmにカットして利用)を添加し、37℃のホットプレート上で十分に乾燥させ、試料乾燥膜フィルターを作成した。セルに純水5gを入れ、前記試料乾燥膜フィルターにより蓋をし、湿度30%、温度30℃下での1、3、5、7、12、18、24時間経過後の試料の重量変化を測定した。その重量変化の傾きを最小二乗法により算出される(nX+m;Xは時間h)のnを水分蒸散速度(単位:mg/h)とし、絶対値としてプロットした。各試料計3回の平均値を求めた。尚、水分蒸散速度が小さいほど、蒸散を抑制したことになる。試験結果を表7に示す。表7より、アルキル基又はアルケニル基の炭素数が20~24で、エチレンオキサイドの平均付加モル数が1.5~4のポリオキシエチレンアルキル又はアルケニルエーテルと、水溶性高分子と皮膚活性成分とを併用した場合においても水分蒸散抑制効果が維持されていることがわかる。
表8~12記載の実施例10~37、比較例11~38の製剤を試験5と同様の条件で試料の重量変化を測定し、水分蒸散速度を求めた。また、専門パネラーを評価項目ごとに5名ずつ用意し、パネラーが製剤を実際に使用し、「塗布後の保湿感」、「翌朝のはり感」、「塗布時のべたつきのなさ」に関して、下記評価基準に従って評価を行い、平均点数を記載した。
また、実施例24~34、比較例28~38の製剤については、1日2回(朝・夜)、2月間の連用評価もあわせて行った。「肌荒れの予防・改善効果」、「毛穴の目立ちやにきび等の予防、改善効果」、「シミ、ソバカスの予防・改善効果」に関して、下記評価基準に従って評価を行い、平均点数を記載した。
その結果を合わせて、表8~表12に記載する。表8~表12より、成分(A)と成分(B)に加えて、(D)皮膚活性成分を配合することにより、閉塞効果、保湿感、はり感、べたつきのなさ等が相乗的に向上することがわかる。

表14記載の実施例38~43、比較例39~42の製剤を試験5と同様の条件で試料の重量変化を測定し、水分蒸散速度を求めた。また、試験6と同様にして、「塗布後の保湿感」、「翌朝のはり感」、「塗布時のべたつきのなさ」に関する官能評価を行った。その結果を合わせて表14に示す。表14より、成分(A)と成分(B)に加えて、皮膚活性成分を配合することにより、閉塞効果、保湿感、はり感、べたつきのなさ等が相乗的に向上することがわかる。尚、比較例41、42においては、POEアルキルエーテルの析出が認められため、官能評価を行っていない。
専門パネラー8名に対し、前腕内側部に2×4cmにマーキングを行い、事前に市販の同じ基礎化粧品3品(化粧水、乳液、クリーム)を塗布し、その後、ナイトパック化粧料(試験品、下記表15)を1.25μl/cm2塗布した。尚、無塗布、化粧品3品のみ塗布したものを比較として試験した。
これらの塗布前、塗布30分後、塗布3時間後、塗布7時間後における角層水分量を、Skicon-200EX(IBS社製)、経皮水分蒸散量をTewameter MPA580(Courage+Khazaka製)にて測定を行った(測定条件:22±1℃、RH50%±5%)。
これらの結果をそれぞれ図2、図3に示す。尚、図2、3中の無塗布は、基礎化粧品、ナイトパック化粧料のいずれも塗布していないもの、3品は、基礎化粧品3品のみを塗布したもの、3品+ナイトパックは、基礎化粧品3品を塗布し、その後、ナイトパック化粧料を塗布したものを示す。
専門パネラー10名に対し、川島ら(日皮会誌、117(3)、275~284頁、2007年)の方法に従い、人工荒れ肌を作成した(前腕屈側部にカップ(直径3.5cm)を装着し、アセトン:エーテル(含有質量比1:1)を6mL添加する。20分後溶媒を除き、揮発させる。その後、10mLの蒸留水を添加し、5分後に水を除く。翌日、同部位に同様の処置を行った。)。
人工荒れ肌部位にマーキングを行い、表16に記載のクリームを、1日2回(朝・夜)、適量を人工荒れ肌作成後、6日間塗布を行った。
これらの荒れ肌作成前・荒れ肌作成後(2日目)、クリーム使用3日目、クリーム使用6日目における角層水分量を、Skicon-200EX(IBS社製)にて測定を行った(測定条件:22±1℃、RH50%±5%)。荒れ肌作成後の角層水分量測定値を基準に、クリーム使用3、6日目のそれぞれの角層水分量との差分を角層水分量変化量(ΔμS)とする。これらの結果を表16に合わせて示す。角層水分量変化量(ΔμS)は、値が大きいほど、改善効果が高いことを示す。
